UPDATE: The network is ordering more episodes of Rules of Engagement and Mike & Molly to make up for Men.

Two and a Half Men's hiatus will drag on longer than previously scheduled.

Although production on the CBS comedy was set to resume Monday, the fate of the hit series is now up in the air. One day after Charlie Sheen was hospitalized for stomach pains, the actor voluntarity admitted himself into a rehab facility.

"We are profoundly concerned for his health and well-being, and support his decision," the network, Warner Bros. TV and show creator Chuck Lorre said in a joint statement.

Meanwhile, Sheen has claimed via text message to RadarOnline that the whole thing was blown out of proportion. "I'm fine," he wrote. "People don't seem to get it. . . . Guy can't have a great time and do his job also?"

It's not known how long Charlie will be away from the set.
